High Andean wetlands of the elevated plateaus of the Andes Mountains of Chile, Argentina, Peru and Bolivia are true oases that sustain life in this arid region. Despite their ecological value, they have been rarely studied ...

High-Andean peatlands are high-altitude wetland ecosystems found throughout the arid central Andes of South America. They form through the establishment of specialized grasses and cushion sedges that are well-adapted to ...

High-altitude hypersaline Andean wetlands are considered stressful environments by the prevalence of extreme abiotic conditions affecting both plant host and fungal root endophytes. Puccinellia frigida (Phil.) Johnston, a ...

Andean wetlands are characterized by their extreme environmental conditions such as high UV radiation, elevated heavy metal content and salinity. We present here the first study on UV tolerance and antioxidant defense of ...

We measured waterbird richness and abundance, and characterized wetland features (altitude, size, and presence of submergent vegetation) of 50 altiplano wetlands, during summer and winter, 1998. We estimated 36,700 individuals ...

The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...

Tropical alpine grasslands of the northern Andes, commonly known as the páramo, provide abundant high-quality water for downstream populations as well as a variety of other environmental services. Yet, very little is known ...
